Feature 1PWM Charging: 12V 24V system voltage is automatically recognized, and the upgraded 3 stage PWM charging algorithm is used to perform periodic or over discharge balanced charging of the battery, effectively preventing battery imbalance and vulcanization, and extending battery life. 2Temperature Compensation and Comprehensive Protection: With temperature compensation, the charging parameters can be adjusted automatically. A variety of load working modes are suitable for different types of loads. Provide overcharge, overdischarge, overload protection, short circuit protection. 3Multifunction: The advanced load starting method is adopted, and the large capacity load can also be started smoothly. The product provides a lattice graphic LCD screen and a one key human machine interface. User friendly browser and dynamic interface design ensure convenient, fast and intuitive operation. With an industrial grade design, the product can work normally in a variety of harsh conditions. With TVS light protection. 4LCD Display: The solar controller is equipped with an LCD display, which can clearly display the status and data, and can easily switch modes and parameter configuration. The large screen LCD display with backlight can adjust the charging and discharging parameters, and has a power off memory function. 5High Efficiency: Our controller can connect two solar panels, which is more efficient than other controllers.Item Type: Solar Charge ControllerMaterial: ABSCharging Type: PWMWorking Voltage: 12V 24V Automatic IdentificationMaximum Charge And Discharge Current: 30AMaximum Photovoltaic Input Power: 390W (12V), 780W (24V)USB Output Voltage: 5V 2AStandby Consumption: 12mAWorking Temperature: -20-+55Terminal Wire Gauge: 28 - 10AWGWaterproof Grade: IP32Applicable Scenarios: Solar Photovoltaic Systems Such As Home Power Generation, Base Stations, Rvs, Yachts, Ships, Etc.Product Size: Approx.16 x 10cm / 6.3 x 3.9in .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Controller1 xUser Manual
